An Introduction to Circle Theorems
A circle is more than just a set of points equidistant from a center point. It's a door to many wondrous mathematical mysteries. Here are some theorems about circles:
- Inscribed Angle Theorem: The angle inscribed in a circle is half of the central angle that subtends the same arc.
- Tangent-Secant Theorem: The angle formed between a tangent and a chord through the point of contact is equal to the angle in the alternate segment.
- Chords and Arcs: Equal chords of a circle subtend equal angles at the center.
